what does it mean to draw and label a line a line segment a ray and an angle
Answer:
A line in geometry is a straight line that goes on infinitely in two directions. To draw a line, you would draw a straight line and add two small arrows on both ends to indicate that they stretch infinitely. To label a line, you would either label two points on the line, or you can assign a letter to the line. (Example: ↔AB or line A)
A line segment is similar to a line, but it doesn't go infinitely in either direction. To draw a line segment, you would draw two points and connect them. To label a line segment, you would label the two endpoints. (Example: ¯AB)
A ray is a line with one side that extends infinitely. To draw a ray, you would draw a point, draw a line from the point going in any direction, and add an arrow on the other end to indicate that it extends forever. To label a ray, you would label the endpoint and some other point on the ray. (Example: →AB)
An angle is the shape formed by two rays that have a common endpoint. To draw an angle, you would draw an endpoint and make two separate rays coming off of it. Then you would draw a short arc in the space between the rays to indicate that it is an angle. There are three ways to label an angle:
1. Label the vertex (∠A)
2. Label a point on one ray, the endpoint, then a point on the other ray (∠BAC)
3. Label the angle with a number or letter (∠1, ∠A)

Answer:
Y= -1x-1
Step-by-step explanation:
The slope is going down in a 1 to 1 ratio, so the slope is -1. The line crosses the x axis at -1, so the y intercept is -1

Answer:
∠ ABC = 48°
Step-by-step explanation:
Since AC = AB , the triangle is isosceles with the 2 base angles being congruent , that is
∠ ABC = ∠ ACB = 4x
The sum ot the 3 angles in a triangle = 180°
sum the angles and equate to 180
4x + 4x + 7x = 180
15x = 180 ( divide both sides by 15 )
x = 12
Then
∠ ABC = 4x = 4 × 12 = 48°

Un buzo profesional está explorando el fondo marino a 48 metros bajo el nivel del mar (−48 m). Al volver a la superficie del mar (0 m), debe hacer pausas de seguridad que evitan cambios bruscos de presión: debe subir nadando verticalmente 8 metros en un minuto, detenerse durante 5 minutos, luego volver a subir 8 metros en un minuto, y así hasta llegar a la superficie.
Respuesta:
31 minutos para llegar a la superficie del mar.
Explicación paso a paso:
Dado que :
Profundidad inicial = 48 m
8 metros = 1 minuto
Tiempo de parada por cada minuto de nado vertical = 5 minutos
Por lo tanto,
1 minuto = (48 - 8) = 40 metros
Tiempo de parada = 5 minutos
1 minuto = (40 - 8) = 32 metros
Tiempo de parada = 5 minutos
1 minuto = (32 - 8) = 24 m
Tiempo de parada = 5 minutos
1 minuto = (24 - 8) = 16 m
Tiempo de parada = 5 minutos
1 minuto = (16 - 8) = 8 m
Tiempo de parada = 5 minutos
1 minuto = 8 - 8 = 0 (superficie del mar)
(1 * 6) minuto + (5 * 5) minuto
6 + 25 = 31 minutos
31 minutos para llegar a la superficie.
Patrick wants to buy a new computer. He already has $275 saved and plans to save $125
each month. The price of the computer is currently $1,850, but Patrick expects the price
to drop by $100 each month. Patrick wants to determine the number of months he will
need to save.
.
If x represents the number of months, then write an equation to represent A, the total
amount Patrick saves.
If x represents the number of months, then write an equation to represent C, the cost of
the computer.
.
Use your equations from part “a” and part “b” to determine how many months he will
need to save before he can buy the computer. Show your work or explain how you got
your answer
Answer:
The answer is below
Step-by-step explanation:
The equation for a linear function is given as:
y = mx + b
where m is the slope of the function (that is the rate of change), b is the initial value of y when x is 0.
a) Since A represent the total amount saved and x represents the number of months. The relationship between A and x is given by:
A = -100x + 1850
The price reduces by $100 each month, while the initial price is currently $1,850.
B) Since C represent the cost of computer and x represents the number of months. The relationship between C and x is given by:
C = 125x + 275
The price increases by $125 each month, while the initial price is currently $275.
C) To determine the amount time needed before he can buy the computer, we use:
A = C
-100x + 1850 = 125x + 275
125x + 100x = 1850 - 275
225x = 1575
x = 7
Therefore it would take 7 months before he can buy a computer
Melissa wants to buy a $25 hat.
The sales tax in her state is 6.25%
How much will Melissa spend on the hat, including the tax?
Using proportions, it is found that, including the tax, she will spend $26.5625 on the hat.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, along with the $25, she pays a sales tax of 6.25% of the $25, hence:
Tax = 0.0625 x 25 = 1.5625.
Total = 25 + 1.5625 = 26.5625.
She will spend $26.5625 on the hat.

A 23 foot ladder is leaning against a wall. The angle of elevation of the ladder with the ground is `58\ degrees.` How far away is the bottom of the ladder from the bottom of the wall? Round your answer to the nearest hundredth.
Answer: 12.19 ft
Step-by-step explanation:
Given
Length of ladder is [tex]23 ft[/tex]
Angle of elevation is [tex]58^{\circ}[/tex]
Suppose the bottom of the ladder is x ft away from the bottom of the wall
from the figure, we can write
[tex]\Rightarrow \cos 58^{\circ}=\dfrac{x}{23}\\\\\Rightarrow x=23\cos 58^{\circ}\\\Rightarrow x=12.19\ ft[/tex]
Thus, the distance is 12.19 ft

Quadrilateral QRST is a parallelogram. Solve for x (3x+5) (9x-17)
Given:
Consider the below figure attached with this equation.
Quadrilateral QRST is a parallelogram.
To find:
The value of x.
Solution:
We know that the sum of two consecutive interior angles of a parallelogram is 180 degrees because they are supplementary angles.
In parallelogram QRST,
[tex]m\angle Q+m\angle T=180^\circ[/tex]
[tex](3x+5)^\circ+(9x-17)^\circ=180^\circ[/tex]
[tex](12x-12)^\circ=180^\circ[/tex]
On comparing both sides, we get
[tex]12x-12=180[/tex]
[tex]12x=180+12[/tex]
[tex]12x=192[/tex]
Divide both sides by 12.
[tex]x=\dfrac{192}{12}[/tex]

Let a = -4.82 and b = 4.35. All of the following statements are true except
The sum of a and b is negative.
The product of a and - b is positive.
The quotient of a and - b is the same as the quotient of - a and b.
The distance between a and b on the number line is 0.47 units.
Answer:
the sum of -4.82 and 4.35 = -0.47
so a is correct
the product of -4.82 and 4.35 = -20.967
so b is incorrect
the quotient of -4.82 and -4.35 is 1.10804597701
the quotient of 4.82 and 4.35 is 1.10804597701
so c is correct
if we subtract 4.35 from -4.82 we get -9.17
so d is incorrect

The area of a rectangular region is 6.2 × 10^3 square feet. The length
of the rectangular region is 1.55 × 10^2 feet. How much does it cost to
surround the region with a border that costs $0.80 per foot?
Answer:
312
Step-by-step explanation:
First we need to determine the width
A = l*w
6.2 * 10 ^3 = 1.55 * 10 ^2 * w
Divide each side by 1.55 * 10 ^2
6.2 ^ 10 ^3 /1.55 * 10 ^2 = 1.55 * 10 ^2 * w / 1.55 * 10 ^2
Changing from scientific notation to standard
6200/155 = w
40 = w
Then we need to determine the perimeter
P = 2(l+w)
P = 2( 155+40)
P =2( 195)
P = 390
Now multiply by the price
390 *.80

We know that : The Sum of the angles in a triangle should be equal to 180°
Given : The Triangle is a Right angled Triangle
It means : One of the Angle in the triangle is 90°
It means : The sum of the other two angles should be equal to 90°
Given : One acute angle is 8x + 5 and the other one is 4x + 9
⇒ 8x + 5 + 4x + 9 = 90°
⇒ 12x + 14 = 90°
⇒ 12x = 76°
⇒ x = 6.333°
The larger angle among the acute angles is 8x + 5
⇒ 8(6.333) + 5
⇒ 50.67 + 5
⇒ 55.67

We know that,
[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]
➪ ∠ 1 + ∠ 2 + ∠ 3 = 180°
➪ 8x + 5 + 4x + 9 + 90° = 180°
➪ 12x + 104° = 180°
➪ 12x = 180° - 104°
➪ 12x = 76°
➪ x = [tex] \frac{76° }{12} [/tex]
➪ x = 6.333°
The value of x is 6.333°.
Now,
Substituting the value of x in eq. (i) & (ii), we have
Angle 1 = 8x + 5
= 8 x 6.333 + 5
= 50.666 + 5
= 55.67°
Angle 2 = 4x + 9
= 4 x 6.333 + 9
= 25.332 + 9
= 34.332°
Clearly, angle 1 is greater than angle 2.
Therefore, the value of the larger angle of the two acute angles is 55.67°.
